Two mares were evaluated because of chronic uterine torsions of 2 and
4 weeks' duration; both were pyrectic, anemic, tachycardic, and
anorectic, had signs of depression, and had an abnormal uterus and
contents on transrectal examination. Both mares underwent cesarean
section for lysis of adhesions from the uterus to the peritoneum,
correction of the torsion, and ovariohysterectomy Both mares
recovered with only minor complications and returned to be used as
riding horses.
Chronic uterine torsion should be considered in mares in late stages
of gestation that have vague clinical signs and transrectal palpation
findings that are unlike those described in typical cases of uterine
torsion. Prognosis for life can be good after treatment by ventral
midline celiotomy, cesarean section, correction of the torsion, and
ovariohysterectomy. [Summary]
